PURPOSE: Report the unusual presentation, clinical course, and cytogenetic abnormalities in a child with multifocal osteosarcoma.
PATIENTS AND METHODS: A 10-year-old boy had multifocal osteosarcoma involving the entire skeleton, pleura, bone marrow, and lungs. He had marked anemia, thrombocytopenia, and severe hypocalcemia at diagnosis.
RESULTS: Despite aggressive chemotherapy, he died from progressive disease 1 month after diagnosis. Cytogenetic analysis of tumor cells within the pleural fluid showed multiple chromosomal abnormalities with amplification of the c-myc oncogene.
CONCLUSION: Multifocal osteosarcoma should be considered in the differential diagnosis of a child with pancytopenia and multiple bone lesions. Amplification of the c-myc oncogene may have had a significant role in the pathogenesis, etiology, and rapid progression of this patient's multifocal disease. Additional studies will be needed to determine the biologic significance of c-myc amplification in multifocal osteosarcoma.
